Emission modification of Sm3+ doped glass due to plasmon effect

By melt-quenching technique, glass samples doped with Sm3+ and containing Ag nanoparticles were synthetized. TEM micrograph and X-ray diffraction patterns are presented. UV–Vis-IR absorption spectra were recorded. Emission spectra of doped samples were collected at room temperature. The results of emission present an enhance with the increasing concentration of Ag nanoparticles due to the plasmon effect causing an enhancement of the electromagnetic field in the vicinity of the metallic nanoparticles, creating a material for photonics and optoelectronic devices.
